I found this book on amazon.com by the American Vision Institute that shows how to improve your vision naturally and I'm curious on buying it because i notice my vision is getting blurry. It seems like it's getting a lot of great reviews. Could they be scamming me for my money? If so why is the book still around? the link is below
